APPARATUS FOR FILLING CANS.

SPECIFICATION forming partof Letters Patent No. 376,195, dated January10, 1888.

Application filed June 3, 1887.4 Serial No. 249,115. (No model.)

To all whom, z'tmaj/ concern.-

Be it known that I, HENRY HERMANN, of Jersey City, in the county ofHudson and State of New Jersey, have invented a new and usefulImprovement in Apparatus for Filling Gans and other Receptacles withPotash and Analogous Powdered or Semi- Fluid Substances, of which thefollowing is a specification. Y The particular object of my invention isto provide a simple and effective apparatus for filling cans with potashor analogous su`ostances which are destructive to the mucous membranewhen present in the air, the desired result being to lill cans with suchsubstances withont permitting their escape to the atmosphere.

In carrying out my invention I employ a hopper which has an outlet atthe bottom and 2o a sliding plate swinging or moving as a sliding valveacross said outlet and havingan aperture corresponding to theoutlet-,and a holder or base to receive upon it a can, and which is hungfrom said sliding plateand is vertically movable to hold the can againstthe aperture in said plate.

In employing this invention one or more cans are placed upon the holderor base, which is below theslidingplate,and said holder is moved so asto force and hold the can or cans against one or more apertures in saidplate, and when said plate is swung or moved across the outlet oroutlets of the hopper the can or caus,tightly applied to an aperture orapertures in the plate,'arc brought to a position below the ontlet oroutlets of the hopper and the material in the hopper is permitted todescend to fill the cans. I also employ in connection with the outlet ofthe hopper a vent-pipe which ex- 40 tends upward to or near to the topof thehopper, and which is adjacent to the outlet of the hopper, so thatas the aperture in the swinging plate comes beneath the hopper-outlet italso passes below the vent-pipe, and for an interval of time onlysufficient to fill the can the aperture in the sliding plate to whichthe can is applied communicates both with the hopperoutlet and withY thevent-pipe, so as to permit the free escape of air from the can as thesubstance passes from the hopper into it.

The invention consists in novel features of construction andcombinations of parts, hereinabove briefly referred to,and hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is 55 a sectional elevation of anapparatus embodying my invention. Fig. 2 is a plan of a plate which isapplied to the lower end of the hopper and which contains the-outlet,and a similar plate sliding as a valve upon the iirst to 6o control theoutlet; and Fig. 3 is a vertical section of the parts at the bottom ofthe hopper, showing the sliding plate as adjustedfto open thehopper-outlet and permitthe escape of material therefrom.

Similar letters of reference designate corresponding parts in theseveral figures.

In the accompanying drawings,Adesignates a hopper, which may be made ofsheet metal, if desired, and which is supported by a suit- 7o ableframe-work, A. The hopper may have a temporary or other cover, A2,composed of boards or other material, and it is also provided with aninletpipe,l3,through which the substance to be distributed into cansenters the hopper. 'Ihe hopper A may be advantageously made of sheetmetal, and in this eX- ample of my invention has at the lower end aplate, C, the bottom surface of whichis iinished truly, so as to form aseat,against which Se may swing a second plate, C. The plate C may beattached to the lower endof the hopper by screws c or other suitabledevices, and has in it an outlet, c. l

The plate C may have in it anaperture, c", terminatingin a cylindricneck, c3, and around this cylindric neck may be placed an annular covercontaining packing, s. In the position of parts shown in Fig. l theaperture c2 is removed from coincidence with the hopper-outgo v IOO Edesignates a holder which is arranged below the plates C C', and ispivoted at the end c to swing vertically, and is sustained in anyvertical position it may be placed by a hanger, C. As here represented,the holder E has holes c', which receive and properly center two cans,and the holder E then being lifted t-he two cans are pressed tightlyupon the rubber s, surrounding the delivery-aperture c2.

Adjacent to the outlet c' from the hopper, and as near thereto asispossible, is a ventpipe, F, which extends upward to or near the top ofthe hopper. The sliding plate C is, as here represented, provided with ahandle, C2, whereby it may be swung or slid under the surface of theplate C, and the holderE is also prolonged to form a handle, E. XVhenthe parts of the machine are at rest, the pla-te C is coincident withthe plate C and the fillingaperture cl is outof line with the outlet efrom the hopper.

Then cans are to be iilled, the Iirst step is to place two of them uponthe holder E and lift the holder to the position shown in Fig. 8,

'thereby holding the cans pressed tight over the circular projectionsaround the filling-apertures cz and upon the rubbers. The holder E maybe held in this position by one hand, while with the other hand graspingthe handle C2 the operator swings the plate C in the direction indicatedby the arrows in Fig. 2, and as the filling-apertures e'Z on the plate Care brought into communication with the outlets c from the hopper thecontents of the hopper are permitted to escape into the cans, and at thesame time the air contained in the cans escapes through the vent-pipe F.It will therefore be seen that my filling apparatus is simple andinexpensive, and yet effective in preventing the escape of dry powder tothe atmosphere.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. rlhe combination, with a illinghopper having an outlet at the lowerend, of a plate swinging as a slide-valve across said outlet and havinga corresponding aperture, and a holder t0 receive upon it a can, andwhich is hung from said swinging plate and is vertically movable to holdthe can to the swinging plate, substantially as herein described.

2. The combination, with a illing-hopper and the bottom plate, C,secured thereon and having an outlet-opening, c', of a second plate, C',also provided with an opening and sliding on the first to bring theopenings into and out of coincidence, and a holder, E, supported by thesliding plate and pivoted to swing vertically in order to hold a cantightly pressed to the opening in said sliding plate, substantially asherein described.

3. rlhe combination, with a illinghopper having an outlet, and avent-pipe adjacent to said outlet and rising to or near the top of theAhopper, of a sliding plate, also having an outlet-opening and coveringsaid outlet, and a holder attached to said sliding plate and movablevertically to hold a can pressed to the outlet-opening of said plate,the outletopening in said second plate being arranged so that by slidingsaid plate the outlet-opening in said second plate is open to thevent-pipe and laps upon the outlet from the hopper, substantially asherein described.
